Pronunciation: [ˈe͡ɪɒtəs] (IPA) 
The spelling of the word "aotus" is relatively straightforward once you understand its pronunciation. In IPA phonetic transcription, it is spelled /eɪˈoʊtəs/. The first syllable is pronounced like the letter "A," followed by a long "O" sound. The final syllable is pronounced with a short "U" sound followed by a soft "T" and an "Əs" sound. This word refers to a genus of nocturnal monkeys found in Central and South America.
Aotus is a genus of primates that belongs to the family of night monkeys, known as Aotidae, and is native to Central and South America. The genus Aotus comprises several species commonly referred to as owl monkeys or night monkeys due to their nocturnal behavior and owl-like appearance. These small to medium-sized primates have large, round eyes that are adapted for excellent night vision, enabling them to be highly active during the dark hours.
Aotus species have a distinctly arboreal lifestyle, making their homes in the dense rainforests and lowland forests of their habitat. They possess a prehensile tail that aids them in swinging from branch to branch and displays a remarkable agility in their natural environment. These monkeys primarily feed on fruit, insects, and other small invertebrates, employing their sharp claws and teeth to locate and capture their prey.
These primates have a complex social structure, often forming monogamous pairs or small family groups. They communicate through a range of vocalizations, including hoots, whistles, and trills. Aotus monkeys are known for their strong pair bonds and exhibit a high degree of parental care towards their offspring.
Due to their intriguing physical features, distinct behavior patterns, and evolutionary significance, Aotus species have been the subject of scientific research as important models in biomedical and immunological studies. This is because they share many characteristics with humans, making them valuable for research purposes, particularly in the fields of vaccine development, genetics, and reproductive biology.
The word "Aotus" is derived from the Greek word "aoutos" (ἀυτός), which means "one's own", "self", or "himself". The name was chosen for the genus of primates, commonly known as the night monkeys or owl monkeys, because of their large, round, owl-like eyes. The name "Aotus" was first proposed by the German zoologist Johann Karl Wilhelm Illiger in 1811, when he described these nocturnal primates.
